futile.options-package: A scoped options management framework

Description

The 'futile.options' subsystem provides an easy user-defined options
management system that is properly scoped. This means that options created
via 'futile.options' are fully self-contained and will not collide with
options defined in other packages.

While R provides a useful mechanism for storing and retrieving options, there
is a danger that variable names collide with names defined by a package that
a user's code depends. These types of errors are difficult to detect and
should be avoided. Using 'futile.options' addresses this problem by properly
scoping variables within its own custom 'namespace'. This is handled by the
'OptionsManager', which acts as a generator for functions that manage user-
defined options.

An added benefit to the package is that default values are automatically
supported in the creation of the bespoke options manager.
